BIOS package for a Lenovo board built on LCFC motherboard EX480 NM-B481, revision 1.0, with a date of 2017-12-27 in the name. The archive is described as holding a 16 MB main BIOS image together with a 1 MB image, most likely the EC or a secondary chip, and is labelled as fully working. The NM-xxxx pattern belongs to LCFC, Lenovo's own ODM. Read and save the original contents of each SPI chip with a programmer before writing, and check every image size matches the capacity of the chip you are flashing.
